gcc shows this error at build
 

8.4 systemd building base system

Hi All,
GCC build shows this :

make[1]: Target 'check-host' not remade because of errors.
make[1]: Leaving directory '/sources/gcc-8.2.0/build'
make: *** [Makefile:2235: do-check] Error 2
make: Target 'check' not remade because of errors.
Should I continue?

When you have build errors, don't just show the last few lines because they are totally uninformative. You need to scroll back and find the actual errors. If you can't do that because they are too far up, repeat the build operation with a log file so that you will have something to examine.

Also you haven't told us whether these are Chapter 5 or Chapter 6 errors, or what stage of the build they come from. It looks like the "make check" stage but how can we tell if you don't tell us? And with gcc, there is a further wrinkle because this is actually a composite build like binutils. We need to know which part of it caused the errors. More information please. And no, you shouldn't continue. gcc is one of the most important packages in the whole of LFS. It has to be built properly.

Thanks Hazel,
I will have to do it tomorrow. It takes a long time as you know. Was in Chapter 6 .

Here is the latest build: this in in chapter 6 building the base system.

Fine. It's the check stage in chapter 6. Always provide this kind of information in future.

Now, if you read Chap 6.31 of the book again, it will tell you how to print out a summary of the results. There's a program called test_summary that will do it for you. There will be a few errors, so don't panic! I believe there are six expected ones in libgcc++ alone.

Then follow the link to the official build and check your errors against those shown. If there are no additional ones (or only one or two of them), you are good to go.

Thanks for the help Hazel
